Question about 1986 Mitsubishi Mighty Max

1 Answer

I don't think my truck is getting a full 12 volts during startup.

I don't think my truck is getting 12 volts during start up. It use to start immediately with just a click of the key and now it takes several times. Also, sometimes while I'm trying to start the engine I turn the key and the starter will just click, but after a couple more tries it will engage the starter again and turn the motor. It seems to turn the motor over at the normal rpm rate, but acts like a weak spark syndrom. I have replaced the coil with a better one and replaced the ignition switch also. 1986 Mits. Mighty Max and well maintained.

The starter is at fault,the contacts are bad in the starter,and it is drawing to much amps from the ignition.

How do I wire a 4-terminal solenoid for this truck? I do not understand what goes on the I and S terminals?



It depends on whether you are running a points or an HEI setup.

The ballast resistor is tied into the coil on a POINTS system, so that it supplies 9 volts to the coil when the motor is running. This lower voltage lengthens the life of the points. During starting however, the coil is fed a full 12 volts to make starting easier.

An HEI system has a full 12 volts fed to it when starting or running, because the switching transistors inside the HEI won't burn out like points will. This is why the two systems are wired differently.

The two small terminals on the starter solenoid are marked as R and S - which stand for Relay and Solenoid, which probably doesn't mean anything to you. SO, think of the two terminals this way - S stands for Start, R stands for Run.

The S terminal is for engaging the starter. The R terminal is for supplying high current battery voltage - to the coil and to the fuse panel. The R terminal is ONLY USED IN POINTS SYSTEMS - the HEI system has no need for it.

I have a 1995 Fxr low rider and changed the ignition module and now I'm not getting full fire from the coil what could it be


check that the new ignition module is running the same voltage as the one you replaced . Some modules run at 12 volts and others run at 7.5 volts with a resistor in the circuit. These start at 12 volts then revert to 7.5 volts to run

It won't start and I think the battery is dead should I get a new one or what?


well, it is kinda hard to say. If the battery is more than 4 years old I would definitely consider it. If not put a charger on it until it has a full 12 volts and then use a load tester to see how it holds a charge.

1971 chevy truck will just shut of any given time. not getting spark. let it sit few minutes starts right up?


check that you have the correct voltage coil installed. IT sounds as if the coil is overheating and failing. There are 2- 12 volt coils on the market. one is a full 12 coil and the other is a duel voltage coil. The wiring allows to start opn 12 volts and as soon as the engine starts runs on 7 volts through a resistor.If you are running a12 volt use with resistor coil on straight 12 volts system you will have problems as you describe

How to tell if alternator is gone on 2000 protege


Hi John, The easiest way to check the alternator is to connect a voltage test meter between the positive and negative battery terminals. A fully charged battery should give 12 and a half to twelve and three quarter volts. Have some one start the engine (making sure the vehicle is in neutral or park and with the park brake fully applied). Voltage during start should not drop to lower than eleven volts. With engine running the voltage reading should be around thirteen volts. Turn on the head lights (full beam) and the heated rear window. The voltage should be maintained or increase slightly above the previous reading. If during start up the battery voltage dropped below that stated earlier the battery will probably need replacement. If the voltages remain constant or drop during the engine run, and if voltage drops below pre start conditions, the alternator requires attention. Regards John

Starts with a jump but cuts off soon as cables are disconnected


Check your batteries voltage you need at least 12 volts.If you don't have 12 volts then put the battery on a 2-4 amp charge for 6-8 hours.Then if the battery does'nt have 12 volts get a new battery.If your battery has 12 volts afterwards and still cuts off then your alternator is faulty.With the engine running your alternators power wire should show 13-15 volts coming out.

I have a 1995 dodge van which wont start due to no spark I have tested right at the coils sec. I do have injector pulse but no pulse at ign coils primary there is power at primary of coil at first we...


A test light connected across the coil primary leads should flash on + off when engine cranks(coil sparks when 12v turned OFF due to collapse of magnetic field).If you get pulsed 12 volts,and no spark from the coil,the coil is bad.If you don't get the pulsed 12 volts,trace back to find out why(the PCM turns the coil ground on and off,12 volts comes from switched IGN source)

Engine on chev. v8 wont start without starting fluid runs fine after it starts


that is strange. how is the battery? one way this could occur is if the battery is too weak during startup to get the computer the right info to fire the injectors so the starting fluid gets it going and then the alternator kicks in and the voltage is present to maintain operation. just one of many possibilities. check this with a volt meter. battery should be 12.5 or better. if you can check while cranking motor without starter fluid and see where voltage drops to.
if it is below 12 volts this could happen. let me know please and thanks for using fixya

If the starter isn't turning it is not an o2 sensor. You need to make sure you are getting power to the starter, use a test light and a voltmeter check and make sure you are getting 12 volts to the starter if you are getting 12 volts from the battery to the starter check and make sure you are getting 12 volts from the ignition switch which will be the smaller wire. If you are getting 12 volts through that wire then the starter is bad. If you are not getting 12 volts or any volts you need to make sure the fuse and relay for the starter are good then check and make sure you have power coming out of the ignition switch going to the starter you will need an electrical schematic for the car to trace the wires to find the correct one.

1991 nissan stanza starter problems


Hi Jim.

When you turn the key, you should at least hear the starter solenoid click. When you turn the key the ignition switch sends 12 volts to the Starter solenoid ( really just a relay). The Solenoid closes and applies 12 volts (at a high current) to the starter motor to crank the engine. If you have a way to measure voltage, you should get 12 volts at the small terminal on the starter solenoid. The solenoid is mounted on the top of the starter motor.If you get 12 volts but no cranking, the solenoid is not working. If you get 12 volts and the starter doesn't crank the starter is defective. At this [point take a small hammer and tap the starter motor, not hard, just medium. Sometimes this will cause the starter motor to catch next time you turn the key. Best bet is to remove the starter motor (with solenoid attached) and take it to an Auto Zone type store where they can check it out for you. Be dure you disconnect the ground terminal of the battery before you attempt to remove the starter motor.

Hope this helps Good luck loringh PS Please leave a rating for me if appropriate Thks
